A ltomey l atented July 7, 1931 PATENT OFFICE FR'AVNKVJ. STOGKBIVIRGER, or ros'ron, MONTANA TRUCK AND TRAILER Application filed July 28,

This invention relates to a truck and trailer therefor andha's for its primary object to pro- Vide, in-a manner as hereinafter set forth,

anapparatus of the aforementioned character embodying the novel construction or bolster's formounting on the truck chassis and on the trailer. r 7

Other objects of the invention are to provide a structure of the aforementioned character, whichwill be simple in COIIStIIlCtIPII, strong, durable, eflicient in its use, and whloh may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan view showing a truck and trailer construction in accordance with this invention.

' Figure 2 is a view in section through the chassis of the truck frame showing the bolster mounted in position thereon.

Figure 3 is a view in rear elevation of the trailer showing the bolster constituting an important feature of this invention mounted in position thereon.

Figure 4 is a view in side elevation of the bolster illustrated in Figure 20f the drawings, the same being shown removed from the truck chassis. I

Figure 5 is a sectional view' showing the brace for the trailer bolster.

Figure 6 is a view in rear elevation showing the bar which is rigidly secured across the rear end portion of the truck frame and to which the trailer is connected.

Figure 7 is a fragmentary detail view in section showing the usual construction of the driving mechanism of the trailer wheels, said trailer being formed from the rear construction of a motor vehicle.

Figure 8 is a fragmentary sectional View showing the means of mounting the standard on the opposite ends of the bolsters.

Referring to the drawings in detail, it will 9 be seen that the reference numerals 1 desig- 1930. Serial No. 471,284.

nate the usual longitudinal side members of a truck chassis which are of the usual configuration and have mounted thereon the transverse filler strips 2 which constitute a portion of the present invention.

K Longitudinally extending bars 3 are disposed on the side members 1 of the chassis and also on the opposite end portions of the filler strips 2, the filler strips being utilized to support the bars 3 at low portions in the side members 1.

A cross beam 4- of appropriate dimensions rests transversely on the bars 3 and is anchored by the bolts 5to the frame members 1. A channel shaped wear. plate 6 is saddled on the beam 4 and anchored by. suitable bolts 7.

A channel shaped wear plate 8 is disposed on top of the plate 6 and'mounted therein is the bolster 9. A pivot bolt 10 extends through the metallic strip 11 on top of the bolster 9 and then through said bolster and the plates 6 and 8 and the beam 4.

Metallic plates 12 are mounted on the opposite sides of the bolster 9 and project from the opposite ends thereof. The portions of the plates 12 which are free of the bolster 9 are inwardly offset and have the bolts 13 extending therebetween. Standards 14; are detachably inserted between the projecting end portions of the plates 12 and have mounted thereon the resilient keeper arms 15 .which are adapted to yieldingly engage the bolts 13 to retain the standards in position and prevent rattling thereof.

A. cross bar 16 has its opposite ends anchored in the side members 1 adjacent the rear ends of said. side members. ,A metallic rod 17 is disposed parallel with the bar 16 and also has its opposite ends anchored in the side members 1 of the chassis. The rod 17 is connected to the bar 16 by the eye bolts 18 and said rod serves to strengthen the bar 16. A trailer designated generally by the reference numeral 19 is connected to the bar -16' through the. medium of the clevis 20 which is rigidly mounted to said bar 16 and pivotally connected to the tongue 21 of the trailer. The usual brace rods 22 also con stitute a part of the trailer 19.
